Gases, treating with liquids. - In order to facilitate the absorption of the vapour of a volatile substance such as acetone in an absorbent liquid such as water, the liquid is distributed in the form of foam in the absorption apparatus. The necessary effect may be produced by adding to the absorbing liquid substances which reduce its surface tension, in the case of water, such as amyl alcohol, saponin, egg albumin, or, preferably, ammonium oleate, potassium stearate, soaps, &c. The gases containing the vapours are passed into pans provided with stirrers and charged with the foaming liquid, or into a tower packed with metallic gratings or domed discs. The absorption may be carried out in a continuous manner on the counter current principle, the liquid drawn off at the outlet being heated to remove the absorbed vapour.
